ANCHORING DEVICE FOR MACHINE-FRAMES.

Specification of Letters Patent.

Patented A110. '28, 1917.

Application filed October 12, 1916. Serial No. 125,281.

To all whom it may concern:

Be it known that I, FRANK FRUSTAGLIO, a subject of the King of Italy, residing at South Porcupine, in the Province of Ontario and Dominion of Canada, have in- Vented certain new and useful Improvements in Anchoring Devices for Machine- Frames, of which the following is a specification. I

This invention relates to certain new and useful improvements in anchoring devices for machine frames.

The primary object of the invention is the provision of a combined saw and log carriage supported upon wheels for transferring the same from place to place, manually operable anchoring members being provided with a carriage for fixedly positioning the latter when desired for use.

In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views Figure 1 is a top plan View of the device. Fig. 2 is a horizontal sectional view of the device.

Fig. 3 is a detail sectional view taken upon line VIVI of Fig. 4.

Fig. 4 is a detail plan view of one portion of the anchoring means.

Fig. 5 is a transverse sectional view thereof.

Fig. 6 is an enlarged detail verticali.sec-' tional view of a portion of the operating means for the anchoring members.

The invention broadly consists of a frame mounted upon wheels 13, as indicated in Figs. 1 and 2, so that the same may be moved from one position to another, and subsequently anchored in position for operation. The frame is especially designed for supporting saw mechanism, parts of wh1ch are incidentally shown, but not described, as they do not enter into the gist of the present invention.

The anchoring means for securing the device in position during the operation thereof, consists of curved anchors or jaws 36 pivoted as at 37 in oppositely-arranged recesses 38 in the lower side rails 39 of the frame 12, the said jaws being arranged in pairs, two pairs thereof being herein illustrated. A plate 40 is provided for each of the jaws 36, a connecting link 41 pivotally connecting each jaw with its respective plate, the said plates 40 being horizontally slidab-ly arranged within guide brackets 42 secured transversely upon the said rails 39. An axle 43 is carried by the inner end of each of the plates 40 for journaling a gear jaws 36 in their elevated-inoperative positions.

.An operating wedge member 47 is slidably arranged centrally longitudinally of the frame 12 through the central portions of the brackets 42 and provided with arrowshaped wedges 48 having teeth 49 upon their opposite edges adapted to mesh with the gears 44. A deck 50 is carried by the frame 12 having a chamber 51therein within which the rear end 52 of the wedge member'47 projects' The said end 52 is provided with teeth 53 upon its upper side with which a pivoted segment rack 54 meshes'whereby the wedge member 47 is longitudinally moved upon oscillating the said rack 54. An operating lever 55 is provided for the rack 54 being pivoted in a mount 56 upon the deck 50 and having a pin and slot connection 57 with the said rack 54, the latter being pivoted to the deck as at 55. A retaining dog 58 is provided for the lever 55 engageable with the mount 56 for retaining the lever 55 and rack 54 as well as the wedge member 47 in its adjusted positions.

The device being adapted to travel upon the wheels 13 is secured in position for operation by means of the anchoring jaws 36 which being normally retracted by the springs 46 when the wedge member 47 is at the forward limit of its movement, a rearward impulse upon the lever 55 rearwardly moves the wedge member 47 with its enlarged portions 48 in mesh with the gears 44 thereby separating the plates 40 and projecting the jaws 36 into firm contact with the earth, such as 58. A limiting pin 59 is centrally carried by. each of the brackets 42 extending to a slot 60 in each of the wedge members 48 forming a guide and limiting means for the same.

lVhat I claim as new is 1. A carriage anchoring means comprising in combination with a rectangular frame having recesses in the side rails thereof, curved jaws outwardly projecting pivoted within the said recesses, guide brackets transversely arranged betweenthe said side rails, plates longitudinally slidably positioned Within the saidbrackets, pivotal link connections between the said j aws and plates, axles carried by the inner ends of the said plates having oppositely projecting ends, retracting springs for the said jaws connecting the said axle ends, and separating means for the said plates.

A carriage anchoring means compris iiig in combination with a rectangular frame having recesses in the side rails thereof, curved jaivs outwardly projecting pivoted ivlthin the said recesses, guide brackets transversely arrangedbetween the said side rails, plates longitudinally slidably positionetl Within the said brackets, pivotal link connections between the said jaws and plates, akles carried by the inner ends of the said plates having oppositely projecting ends, retracting springs for the said javvs connecting the said aXle ends, separating means for the said plates, gears journaled upon the said axles within the said brackets, a Wedge i'heinber centrally arranged of the frame longitudinally shittabl'e therein extending through the said brackets and having toothed Wedge portions in constant mesh with the said gears, and manual shifting means for the said Wedgemember positioned outwardly of one end of the frame.

3. A carriage-anchoring means, including an anchoring element fulcrumcd upon said carriage, a slidable member positioned upon the carriage, a link intermediate of and conneetedto said slidable member-and said anchoring element, a bracket mounted upon the carriage, an actuating member received by said bracket for said anchoring element, said latter member and said slidablemember being inter eared, and a pressure-delivering member; adapted to deliver its pressure to said slidable member.

4.; Acarriage-anchoring means, including anchoring elements fulcrumed upon said carriage, slidable members upon said carriage, links intermediate oi', and connected to said slidable members and said anchoring elements, a bracket mounted on said carriage, an actuating member received by said bracket, for said anchoring elements, said actuating member and saidslidable' members being intergealedfthe shafts of the gearing of the slidable members being resiliently connected together, the normal action thereof retaining said anchoring elements in inoperative osition.

A carri'age anchoring'meaiis, including anchoring elements ful'cr'ihned upon sai' carriage, slidable member's upon said carriage, links intermediate of, and connected to said slidable members and said anchoring elements, a bracket having upper and lower spaced members secured upon the carriage, a longitudinally slotted wedging member received between the membersof said bracket, said iveclging member and said slidable members being intergeared, the shafts of the gearing of said slidable mom'- bers being resiliently connected together, the

normal 'a'c'tion thereof retaining said anchoring element's ih'in'operative position, the slot of said Wedging member receiving a guiding pin'between the members of said bracket.

In testimony'tvhereof I afi ix my signature.
